The Heath Ledger documentary trailer just dropped and it'll make you cry

The first trailer for the highly anticipated I Am Heath Ledger documentary has arrived, and it's sure to break your heart.

Almost 10 years after Heath Ledger's tragic and untimely death, the 90-minute documentary is set to premiere on April 23 at the Tribeca Film Festival, featuring interviews with the actor's closest family, friends, and colleagues as well as never-before-seen home footage of the star.

"Heath was the most alive human," musician and friend Ben Harper says in the trailer. “And if it wasn’t on the edge, it didn’t interest him."

Ben joins a slew of famous faces in the bittersweet documentary, including fellow Australian actors Ben Mendelsohn and Naomi Watts, and Brokeback Mountain director, Ang Lee. Childhood friends and Heath's sister, Kate Ledger, also appear, though notably absent is Michelle Williams, Heath's ex-partner and mother of his 11-year-old daughter, Matilda.

The 28-year-old actor died from an accidental overdose of prescription medications that included painkillers, sleeping pills, and anti-anxiety drugs. He was found in his Manhattan apartment on January 22, 2008.

The three-minute clip reveals plenty of intimate footage of The Dark Knight star -- many of which he had filmed himself -- reminding us of his aspirations to be a director.

His trademark smile, together with clips from some of his most successful movies, including Lords of Dogtown and Brokeback Mountain also feature throughout.

The documentary will be the latest episode of the Spike TV original documentary series I Am, which profiles the lives of notable individuals throughout history. Previous episodes have been dedicated to John F. Kennedy Jr., actor Steve McQueen, and more.
